IdeasUnlimited Reviews & Testimonials
Kimberly Weber President and Founder at Iowa Home Care

BPO Review from Kimberly Weber
We brought on IdeasUnlimited to help with our back office work so our nurses and staff could stay focused on clients. They handle scheduling, reports, emails, and client inquiries, and they picked up new tasks fast with very little training. The time we save is huge, and it makes our daily operations smoother. What I like most is they really try to fit into how we work, so it feels like they are part of our own team. The onboarding took a little time, but once we got set, everything has been running well.

BPO Review from Miriam Woodward
IdeasUnlimited has been a dependable partner for us at De Dios Consulting. They handle our scheduling, emails, research, and reports, which freed up time for us to focus on clients. What I value most is how quickly they adapt and how much they feel like part of our team. The only challenge was getting them up to speed on a few tools, but once they learned, everything has been smooth.

Medical Review from Jeffrey Bill
Working with IdeasUnlimited has been a real help for us at Sunrise Treatment Center. We brought them in to handle our medical billing so our staff could focus more on patients. They learned our system fast and cut down on errors which meant we got paid quicker and had better cash flow. Communication has always been easy and they adjust when we need something changed. What stood out most is how detailed and reliable they are. Nothing is ever perfect but they came pretty close.

Lead Generation Review from Joachim Fong
For the past year, Callbox has provided us with satisfactory lead generating and lead nurturing services. They were instrumental in securing attendees for our events, scheduling client appointments and facilitating the sale of one of our benchtop systems. Their professionalism in conveying our product attributes and valued solutions to prospective customers has brought us results.

Lead Generation Review from Jonathan Anderson
I’ve used Callbox now for about four months for my internet marketing company. The first two months they did not pay off. However with some additional training on my part, they started to close a higher percentage of my target audience. They’re really smart, nice and are really working hard to keep my business. My dedicated team keeps me up-to-date through frequent communications. My R.O.I is getting stronger and my CPA is starting to drop.

Appointment Setting Review from Ted Calvin
Charted Energy has enjoyed a productive relationship with Callbox. They have done a great job of helping us target prospects within the markets we serve as well as qualify leads and set up appointments with decision-makers. Callbox has generally exceeded the number of leads per week we expected and provides a good value by enabling our inside sales team.

Sundar Kasyap's Review Sourced from Google
Our small clinic in Texas was struggling with billing and insurance claims. Invensis’ Revenue Cycle Management services turned that around quickly. Claims are processed faster, and denials have decreased. They're professional, easy to work with, and understand the U.S. healthcare system inside out.

It was a very productive and swift process. Starting from the interview, to assessments. Everyone was punctual and need not wait for a week or so for updates. They give updates immediately no need for the long wait and suspense. Keep it Up!!

I had a truly outstanding experience with 1840&Co throughout the entire recruitment process. From the very beginning, their team demonstrated professionalism, clear communication, and genuine care. What stood out most was the consistent follow-up—they kept me informed at every step, making the process feel smooth and well-organized. I always felt supported and valued as a candidate. I’m incredibly happy to share that I’ve been offered a new role, and I couldn’t be more grateful to the 1840&Co team for making it all possible.
